Hi,

I have designed an user registration form for users who need to enter their usernames in Korean characters.

I am aware that WordPress doesn't accept non-latin characters but I have implemented this filter which works properly when a user is created at the back-end:

add_filter('sanitize_user', 'non_strict_login', 10, 3);
function non_strict_login( $username, $raw_username, $strict ) {
if( !$strict )
return $username;
return sanitize_user(stripslashes($raw_username), false);
}

However, in the registration form at the front-end there is still a validation.

Is there any way to avoid this registration form username validation?

Thank you so much.

Hello,

There isn't such kind of built-in feature within Toolset or WordPress by default, and it is not safe to use sanitize_user filter as you mentioned above, this will conducts other unexpected result.

In my opinion, you can use's nick name to store the Korean characters.
